Survey: CEO Candor On the (Steep) Decline

• The Find: Top U.S. CEOs issued 21 percent more confusing and misleading statements last year than they did in 2006 -- and 85 percent more than they did just five years ago.

• The Source: The 2007 Rittenhouse Rankings survey.

The survey, which evaluates candor in annual shareholder letters, shows that confusing and misleading statements or "dangerous fog," increased 66 percent in the survey up from 39 percent five years ago. In contrast, statements that require simple clarification or add useless clutter or "benign fog," declined to 34 percent, down from 61 percent.
